Phylum Entoprocta is a group of microscopic animals that are commonly referred to as "Goblet Worms" or "Loriciferans" due to their unique morphology. These synonyms reflect the physical structure of these animals, as they have a goblet-shaped body that is held within a protective case or lorica. Another common name for this phylum is "Kamptozoans", which refers to the fact that Entoproctans are sessile filter feeders and remain stationary for most of their lives. Additionally, Entoprocta are sometimes called "Hydrozoan Worms" due to their resemblance to certain colonial aquatic invertebrates. These varied names demonstrate the level of interest and fascination that these enigmatic creatures have generated among zoologists and biologists.
